Compare Technics EAH-AZ100 Earbuds vs Denon Perl Pro True Wireless Earbuds

ANC is widely rated top-tier for everyday noise and transit rumble, but several reviews stop short of calling it the absolute best in the category. Noise control is highly adjustable, with adaptive ANC plus granular sliders that let you tune intensity and reduce pressure effects.

ANC effectiveness is usually rated good but not class-leading; it can handle commute rumble well, yet several reviewers say Sony/Bose options suppress more, especially in the upper ranges. Noise cancelling and awareness modes are often limited in fine control, with some reviews noting on/off style behavior and few intensity tweaks compared with competitors.

Android compatibility is good overall, and Android users with aptX-capable Snapdragon devices can get the most from Lossless/Adaptive modes; on other phones it still works well but with fewer codec benefits.

The Technics Audio Connect app is feature-rich (ANC, EQ, multipoint, spatial settings), but some reviews call the interface clunky or menu-heavy.

The companion app is feature-rich for personalization, EQ, control mapping, and updates, but some sources mention slow loading or occasional instability, and several note it is effectively required to get full value.

Several reviews explicitly note aptX codecs are not supported.

aptX support is a highlight, with repeated mentions of aptX Adaptive/Lossless (and sometimes aptX Voice) as a key advantage for compatible Android devices.

Where tested, audio-video sync is reported as excellent with minimal to no noticeable lag.

Video latency is generally reported as well controlled, with reviewers noting little to no audio-video sync issues during typical streaming and YouTube viewing.

Bass is repeatedly called deep and unusually controlled for true wireless, though one review found it can feel heavy or change with ANC settings.

Bass is frequently praised as impactful and well controlled, with Immersion mode letting you add heft without obvious bleed; a few listeners still find the default or certain profiles bass-light or overly sculpted.

Battery life is commonly reported around 10 hours with ANC on (AAC) plus substantial case recharges, with lower figures when using high-res modes.

Battery life is marketed as long, but real-world reports vary, with at least one standardized test landing closer to about six hours; most still consider it adequate for daily use.

Bluetooth stability is generally reported as reliable with few dropouts across devices and environments.

Bluetooth stability is mostly strong with quick reconnects, though at least one review reports occasional stuttering in specific conditions.

Build quality is generally viewed as solid and premium-feeling, with durable housings and a well-made overall package.

The case is generally pocketable and premium-feeling, but some reviews mention weak magnets, slight rattle, or scratch/scuff issues.

The charging case is often described as somewhat bulky but generally sturdy with strong magnets; a few comments mention hinge/handling quirks.

Charging is praised for USB-C plus Qi wireless and quick-charge support; full recharge times are typically a few hours.

Charging is a strong point with fast-charge support and both wired and wireless options, though a small number of users report the case can get warm on a wireless pad.

Codec support is strong (SBC/AAC plus LDAC and LC3/LE Audio features noted), appealing to both iOS users and Android audiophiles.

Codec support is broad, including aptX Adaptive and aptX Lossless alongside AAC/SBC; the main caveat is that benefits depend on having a compatible source and LDAC is missing.

Comfort is widely rated high thanks to a smaller/lighter fit, though some users may still experience fatigue or fit variability over long sessions.

Long-wear comfort is highly personal: some find the fit secure and comfortable, especially with wings, while others report pressure, heat, or discomfort due to the large shells.

Design is viewed as premium and more compact than the prior model, though not everyone finds it the sleekest-looking option.

Design is distinctive and polarizing: the large circular faceplate stands out, but many note the buds are physically big and may look or feel awkward in smaller ears.

Multiple ear tip sizes are commonly included, helping most users achieve a seal, though tip choice remains key to fit.

Ear tip options are generous, typically including several silicone sizes plus at least one foam set, which helps comfort and isolation when matched correctly.

EQ customization is a strength, often cited as an 8-band EQ plus presets that can significantly change the sound.

EQ options are strong for the category, typically including a 5-band ProEQ plus an Immersion bass slider to fine-tune tonality after personalization.

Find My/location features are present, but feedback varies; some appreciate the feature, while others complain the locating beep or accuracy is limited.

Frequency response accuracy is divisive: some praise a balanced, natural tuning once updated, while others cite measured or perceived tonal issues out of the box that may require firmware and EQ.

Included accessories are a highlight, with multiple tip sizes, foam options, and stabilizing wings helping users dial in fit and seal.

Instrument separation is frequently praised on busy tracks, helping the AZ100 stay clean and layered.

Instrument separation and imaging are commonly highlighted as a standout, with precise placement and clean layering across busy mixes.

LDAC support is frequently highlighted for higher-quality Android streaming, with the usual battery-life tradeoff.

LDAC is repeatedly called out as not supported, so Android users who rely on LDAC for high-bitrate Bluetooth may prefer alternatives.

Clarity at higher volumes is typically strong, with multiple sources noting low distortion and intelligible detail even when played loudly.

Voice noise reduction is often effective at cutting wind and background noise, though aggressive processing can create artifacts.

Noise and wind reduction on calls is frequently reported as effective, helping keep speech understandable in busy or windy environments.

Call quality is mixed: many find it usable or improved, while others report robotic processing or, in one case, serious call glitches.

Call quality is generally above average, with voices described as clear and intelligible; a few reviewers still note slight processing or that top rivals edge it out.

Midrange is generally clear and natural for vocals, with occasional notes that bass-heavy mixes can push voices slightly back.

Midrange is generally clear and present, but can sound forward or radio-like depending on the AAT profile and firmware, so some users prefer minor EQ adjustments for balance.

Multi-platform use is supported across phones and computers, but fidelity and feature access can vary by platform, with iOS often limited to AAC and Android benefiting more from aptX.

Three-device multipoint is a major differentiator and is often described as seamless; occasional switching lag is mentioned but not common.

Multipoint connectivity is a consistent win, with reviewers reporting reliable dual-device pairing and fast handoff between phone and computer/tablet.

Passive isolation depends heavily on getting a good seal; with the right tips, attenuation is described as decent, but it is not the main selling point versus active cancellation.

Preset EQ options are generally useful, though some (like extra-bassy modes) may be too much for neutral listeners.

Personalized AAT profiles can produce dramatic, often positive changes, but results vary by listener and tips; some profiles trade a sense of spaciousness for extra punch or focus.

In-ear sensors for auto play/pause are commonly mentioned and generally work as expected, with options to change or disable behavior in the app.

Case finish durability is mixed, with some noting scratches/scuffs and others calling it relatively scratch-resistant.

Setup is mostly straightforward, but the lack of a case pairing button and some app UX quirks can add friction.

Setup and daily usability are good once configured, but some reviews describe the experience as less polished than rivals because controls and tuning can require initial tinkering.

Reviews consistently praise the AZ100 for highly detailed, spacious sound with strong dynamics; a few note the default tuning can be bass-forward or benefit from EQ.

Sound quality is the main strength: many reviews describe a clean, low-distortion, spacious and highly detailed presentation, especially after Masimo AAT personalization and/or EQ tweaks, though a minority found stock tuning or earlier firmware disappointing.

Soundstage is a standout: multiple outlets describe an immersive, wide presentation that feels larger than typical earbuds.

Soundstage is widely described as unusually wide and open for true wireless, with good spacing; a few reviews note it can feel a bit flatter in depth compared with the very best rivals.

Dolby spatial audio/head tracking is supported and can add immersion, but some reviewers find it subtle or prefer it off for music.

Spatial audio gets mixed reactions: some find it immersive and bubble-like, while others call it subtle or underwhelming, and it is typically not head-tracked.

Fit stability varies: many report a secure hold, while some reviewers experienced looseness or buds falling out during vigorous movement.

Stability is usually good when the right tips and wings are used, though some users report slight movement during chewing or vigorous motion without added support.

Touch controls are responsive and highly configurable, with the main complaint being occasional over-sensitivity.

Touch controls are commonly described as responsive and highly customizable, with reliable gesture detection and audible feedback.

Transparency/ambient mode is strong and adjustable, but some reviewers note hiss at higher levels, an unnatural voice-focused mode, or not enough outside sound for awareness.

Transparency or social mode is usable but mixed: some call it smooth and subtle, while others find it less natural, occluded, or slightly artificial versus AirPods-class passthrough.

Treble is described as airy and detailed without harshness, but a few critics wanted more sparkle or presence.

Treble tends to be detailed and airy, but reports vary from smooth and controlled to tinny or over-sharpened on older firmware or specific personalized profiles.

USB-C charging is consistently supported and frequently mentioned as a modern convenience.

USB-C charging is consistently supported and frequently mentioned as the standard wired option.

Voice assistant integration is supported through touch controls, with reports of common assistants working reliably when mapped.
